2 OVERVIEW

Section-3 has some introductory remarks. In Section-3.1, the WBS Dictionary entry of the Experimental Facilities

Utilities is given. Section 4 lists all environmental and utilities requirements. Section-5 summarizes all the

Experimental Facilities Utilities Specifications, by dividing them into four categories; Electrical, Water, Liquid

Nitrogen and Gas supply and exhaust system. Section-6 provides a list of its technical interfaces with the other parts

of the NSLS-II project and, finally, References are given in Section-7.

3 INTRODUCTION

This document describes a standard package of utilities for NSLS-II beamlines. Requirements and specifications of

individual beamlines may in part differ from this standard package to meet specific needs (e.g. higher power

consumption, or greater water flows). These additions are outside the scope of this document and will be defined in

the individual beamline RSI documents.

The document also defines the overall requirements for the beamlines within the facility and thus provides a

specification to the Conventional Facilities Division for the interface points (mainly on, or around, the SR tunnel

roof).

The installation of the Beamlines Utilities is a major activity for completion of the beamlines. In terms of

installation sequence, the Beamline Utilities follows the installation of the enclosures and only then can the

installation of the beamline optics and end station proceed. The installation of the Beamline Utilities is on the

critical path for installation of beamline equipment.

3.1 Experimental Facilities Utilities: WBS Dictionary Definition

Specification of the utilities needed for use by Experimental Facilities includes experimental floor exclusive of

those required for supporting beneficial occupancy of the space (HVAC, lighting, convenience power, etc.). Does

not include activities related to bringing these utilities from the facility drop off to the beamline.

4 EXPERIMENTAL FACILITIES UTILITIES REQUIREMENTS

4.1 General

The Synchrotron Facility is designed to operate continuously 24 hours per day, 7 days per week (≥ 5,000 User

Beam Hours per year). The design life of the beamline utilities system shall be a minimum of 25 years.

The environmental conditions (temperature, temperature stability and humidity) are defined in the document

“Experimental Facilities Requirements, Specifications and Interfaces for the Ring Building and Experimental

Floor”, RSI Document No. 1.04.05.AB.

The utilities system shall be designed such that no personnel hazard or damage to any component within the

utilities system can result from any interruption to, or loss of, these services.

Work according to these requirements and specifications includes: detailed design, review and approval,

manufacture, installation, testing, commissioning, documentation, maintenance and coordination with the ES&H

division.

The following tasks are included in the Scope of Work for the Beamline Utilities:

a. Design, review and approval of the mechanical services distribution and electrical systems;

b. Production of the manufacturing, installation and as-built drawings as well as all procedural and

maintenance documents;

c. Supply of materials;

d. Manufacturing of custom parts;

e. Purchase of all parts;

f. Clean assembly of systems;

g. Inspection and testing;

h. Installation at the beamline, including building permits as required for the works;

i. Preventing damage to, and maintaining the integrity of, all enclosures (a.k.a. hutches, or experimental

stations);

j. Precise work coordination with the enclosures contractor;

k. Commissioning, testing and certification of the installation;

l. On-site training, for operation, maintenance and fault diagnosis.


7

4.2 Communication and data transfer

Communications to the beamline hub shall be via fiber-optical cable from a local Intermediate Distribution Frame

(IDF) to the Beamline hub (normally on the roof of the beamline FOE).

The interface point to the XFD scope (and budget) will be at the IDF.

The FO cable from the IDF to the beamline router will comprise 12 individual fibers, and may be high

quality multimode (e.g. OM3) with a typical data rate of up to 10 Gb/sec per fiber.

The local hub will provide a 1 Gb/sec sub-network for the beamline control system from a 24 or 48 port

CISCO or equivalent router (the specification of this device can be decided later).

The FO connection shall provide access (as required) to other sub-networks (e.g. to request an insertion

device move from the accelerator network).

The FO connection shall provide (fiber optic) network access for User data storage at a local (shared)

RAID array (probably located in the LOB),

Access to the internet for staff and Users shall be accomplished via the FO connection to the beamline.

This external access to (and from) the internet may be used for remote control and monitoring of the

beamline or external (User) storage.

The communications system shall include provision for two phone outlets per beamline.


8

4.3 Standard Requirements for Beamline Utility Services at the Point of Usage

The scope of supply for the standard utility services to all Beamlines is as follows;

a. Electrical power distribution from the interface points for both sensitive and non-sensitive power at the

ratchet wall including sub-panel distribution boards with appropriate and properly labeled circuit breakers

at each enclosure or experiment area, cable trays, all the electrical outlets in the enclosures and along the

beamline and wiring to light fixtures, fans, hoists, etc. inside the enclosures. It also includes electrical

power outlets in the hutch, cabin and user area;

b. Electrical grounding system from the interface point on the SR tunnel roof;

c. De-ionized (process) water distribution for beamline components needing cooling due to photon heatloads.

See Table 3 Water Services Specifications;

d. Chilled water distribution to all equipment racks and some items of end station equipment such as furnaces,

compressors, etc. See Table 3 Water Services Specifications;

e. Liquid nitrogen distribution from the local interface point on the SR tunnel roof;

f. Compressed nitrogen gas from the local interface point on the SR tunnel roof;

g. Facility compressed gas (compressed air);

h. Experimental gases distribution from gas cylinders into hutches;

i. Ambient temperature sensor installation inside enclosures (hutches);

j. Oxygen depletion sensor installation where required following calculations defined in the SBMS “ODH

Classification/Controls” subject area to determine the need and posting requirements. This may include

optics hutches with LN2 cooled monochromators and compressed nitrogen gas delivery systems, and all

experimental stations (unless it can be shown that there will NEVER be any chance that a cryogenic system

or compressed N2 gas will be used in the enclosure, in practice this is very difficult to do – an alternative

would be to engineer the hazard out of the system, eg with flow restrictions, fans etc), according to ES&H

requirements;

k. Communications, including: Beamline LAN with switches and racks (including Ethernet outlets in the

hutches, cabin or user area), and telephone lines (two per beamline);

l. Cabling and piping support structures, including necessary pylons and roof supports for cable trays, for all

utilities as well as EPS and PPS cables;

m. Gas-exhaust system for ventilating fume hoods, etc. from the User area or (less likely) from within

enclosures to a common exhaust manifold.

n. Air exchange system for forcing filtered experimental hall air into the hutch (this will then leak out via

labyrinths and custom air outlets). The fans are mounted on the hutch roofs and air passes in through a vent

labyrinth; the fans will be included in the hutch or cabin contracts and will be wired up under the beamlines

utilities work package. This work is entirely covered by XFD budgets.

o. Specialized hazardous gas exhaust (where this is required due to Health and Safety concerns that the gas

exhaust system is inadequate) would be a special utility request and needs to be coordinated with CFD and

ES&H division. This is outside the scope of this document. This system would probably be constructed in

polypropylene for chemical resistance and operation in the 32-150F (0-65C) temperature range.

p. Emergency lighting and painting of the floor may be required in the region of an emergency egress duck-

under. If required, this will come under the Beamline Utility Services work package.

q. Emergency showers and eyewash stations are required within unobstructed 50’ of positions where

corrosives are being handled. This is addressed within the document “Experimental Facilities

Requirements, Specifications and Interfaces for the Ring Building and Experimental Floor”, RSI Document

No. 1.04.05.AB

4.4 Requirements for Beamline Utility Service Interfaces.

The utility connections (or provision for their later easy addition) generally located on the SR tunnel roof are to be

included as part of the basic building design, and will be detailed by the Architect. The full requirements

specifications are provided later in this document.


9

The scope of supply for the beamline utility service interfaces on the SR tunnel roof is as follows:

a. Electrical power interface points for sensitive and non-sensitive (“clean” and “dirty”) 120V and 208V 3-

phase electrical power including provision for up to four circuit breakers (in total), located within a load

panel on the inside building wall above the SR tunnel roof;

b. Electrical grounding system interface point;

c. De-ionized (process) water at interface (flow and return) points on the side of the SR ratchet shield wall at a

position roughly in the middle of a future FOE, and as close to the ceiling as possible. It is expected that

this will be approximately 20’ downstream from the beamline penetration of the ratchet wall and

approximately 4’ below the top of the ratchet wall, with isolation valves, if appropriate, within the SR

tunnel. The XFD scope of supply will include a second isolation valve inside the FOE;

d. Chilled water interface (flow and return) points expected to be on top of the SR tunnel fixed to a 6’ high

unistrut frame with appropriate quarter turn isolation valves and downward pointing connection points at a

height of approximately 5’;

e. Liquid nitrogen system interface point expected to be on the SR tunnel roof attached to the same unistrut

frame as the chilled water, and at the same height, with an appropriate cryogenic isolation valve and

connection bayonet;

f. Gaseous nitrogen interface point expected to be on the SR tunnel roof adjacent to the liquid nitrogen

interface point, with an appropriate gas isolation valve and connection fitting;

g. Facility compressed gas (compressed air), from within the SR tunnel with a quarter turn isolation valve, as

appropriate, passing through the SR ratchet shield wall immediately adjacent to the DI water pipes,

terminating at an interface point outside the SR tunnel;

h. Communications, interface point including:

i. Fiber optic cabling from the local IDF (Intermediate Distribution Frame), to the beamline interface

point either in the service building or at intermediate points between service buildings (total 10

interface points). Splicing of the FO cable is to be avoided. The XFD scope of supply, on each

beamline, will include running of FO cable around the inside building wall to a point close to the

beamline and then be routed over the walkway on top of the SR tunnel to the appropriate rack on

the beamline;

ii. Connection point on the unistrut interface panel (also used for chilled water and LN2) for two

telephone lines per beamline (these lines will be run in copper cable from the nearest Service

Building);

iii. The specifications for the FO cables are included in the Communications RSI.

i. Gas-exhaust system manifold designed to meet the requirements outlined in Table 7 Gas Extraction

System Specifications.

j. Provision shall be made in the utilities piping supports for the later addition of a 6” diameter metal or

plastic Helium gas recovery pipe. This shall go around the facility above the SR tunnel roof, and provision

shall be made later for;

a. connection to a helium gas bag (probably to be located below the building roof, suspended

between bar joists),

b. a compressor in a separate small building, and

c. trailer parking for the compressed gas bottles.

The CFD scope is no more than provision of brackets and space, for the recovery pipe on the pipe support.

k. A flow and return “stub” for connection to the fire sprinkler system shall be provided adjacent to the

beamlines, above the SR tunnel roof. See the document “Experimental Facilities Requirements,

Specifications and Interfaces for the Ring Building and Experimental Floor”, RSI Document No.

1.04.05.AB.

l. A tepid water system shall be provided around the facility on the inside of the outer wall adjacent to the

access corridor to allow for emergency shower stations to be added as required. See the document

“Experimental Facilities Requirements, Specifications and Interfaces for the Ring Building and

Experimental Floor”, RSI Document No. 1.04.05.AB.


10

4.5 Experimental Facilities Utilities: Provision of Services on Building Beneficial Occupancy.

The following services will be provided around the facility at the time of beneficial occupancy of the building:

1. Electrical power cables;

2. Electrical grounding system;

3. De-ionized (process) water with holes in the SR tunnel ratchet wall, and interface points;

4. Chilled water;

5. Facility compressed gases (Compressed air and N2 gas);

6. Tepid water loop around the walkway for the later addition of eyewash/shower stations around building

periphery and at beamlines as the facility gets built out.

7. Liquid nitrogen system;

8. Non-hazardous gas-exhaust system.

The following services will be installed to specific beamline locations, as needed:

9. Fiber optic cabling;

10. Telephone connections;

11. Beamline transformers and load panels.


11

5 EXPERIMENTAL FACILITIES UTILITIES SPECIFICATIONS

5.1 Electrical Systems

The AC Electric Power distribution to beamlines originates from 480V main distribution panels, one per Storage

Ring (SR) cell, fed from the service buildings. These load panels serve SR equipment and all beamlines.

Each beamline is powered by two, 30 kVA transformers, one for instrument “sensitive” and one for normal “non-

sensitive” loads. The maximum design load, for each beamline, which is the sum of instrument and normal loads,

shall not exceed 30 kVA (i.e. the supply transformers typically work at 50% of rated capacity to keep the noise

level low). Each beamline will have two load panels, one for instrument and one for normal loads. Each panel will

supply 3 phase 208 VAC or single phase 120 VAC circuits. These panels will serve as main panels for each

beamline. The main 480VAC distribution panel, the 30 kVA transformers, and the 208VAC panels are all located

on the inside building wall above the SR tunnel roof (mezzanine equipment area).

The definition of a beamline, in this context, is all the equipment attached to a single section of ratchet wall face

(i.e. a canted beamline will utilize the same electrical supply, unless agreed otherwise).

All of this equipment is to be supplied by CFD.

Total Power Voltage Amps

Power-1 (sensitive) 30 kVA 120/208 100

Power-2 (non-sensitive) 30 kVA 120/208 100

Average operating load per beamline 50% of above values

Maximum operating load per beamline 100% of above values

Supply Voltages

120 VAC single phase power + 5%

208 VAC three phase power + 5%

480 VAC* three phase power + 5%

Supply Frequency

60 Hz + 0.1 Hz

Beamline Power – Heat Removal

Heat dissipated to the building air 40% of total

Heat dissipated to the chilled water system 60% of total

Table 2 Electrical Services Specifications

*480VAC mains will not be provided to beamlines as standard.

The estimated average operating load across all beamlines is to be used to define the size of main

transformers supplying the building.

The maximum operating load per beamline is to be the installed power capability for any individual

beamline.

Mains supply voltage and frequency to be installed as per NFPA 70, National Electric Code, tabulated

above for reference only.

Higher power or voltage requirements will be provided as required; this is expected to be unusual, and

would need to be called up in the RSI for that specific beamline utility system.

Long beamlines with satellite buildings will have the satellite building systems (e.g. lights, security,

HVAC) powered separately from beamline utility power. Power for the beamline equipment in the remote

station will be provided from the sensitive and non-sensitive transformers on the internal wall above the SR

tunnel roof to retain a common supply across the whole beamline.

See Appendix 1 for background information on the estimation of electrical loads.


12

Emergency generators are reserved for equipment that would have Life Safety consequences if power is

lost. It should be noted that no beamline equipment has been identified in this category. Note that it is

likely that cold rooms or freezers in the LOBs will require a UPS, these are outside the scope of this

document but will be considered on a case by case basis and be financed from the LOB fitout budget.

Uninterruptible Power Supplies will be installed in beamline racks on an “as needed” basis. These will be

used to provide power continuity to critical servers etc, and are included in the beamline control system

costs (i.e. XFD budget) and not the utilities distribution.

Cryocoolers used for keeping monochromator crystals at liquid nitrogen temperature may be fitted with a

dedicated UPS (typical single phase power consumption of a cryocooler is 750W), when the cost and risk

of unit power failure warrants expenditure on such a system.

Any UPS used shall be sized appropriately for the load and the risk / duration of power outages.

Electrical power distribution design shall meet all relevant codes and standards (e.g. NEC, OSHA, DOE

Code 10 CFR 851 and BNL site regulations).

Typically a beamline may have single phase mains outlets at 1m intervals along the internal in-board side

of the hutch. External mains sockets will at least double this number; in total this could amount to 80

sockets for clean and dirty power combined.

5.1.1 Electrical Cable Trays above Walkway

Two cable trays will be provided around the building exterior wall at a height of >4m, above the walkway, at about

300mm spacing, vertically. This is to be used wherever a convenient run from a beamline to an LOB is on the

outside diameter of the building, rather than via the SR tunnel roof.

Cable trays are required for:

One for communications, ethernet, fiber-optics, and other low level signals (including fire alarm cabling - if

this is permitted),

One for noisy signals and/or voltages (≥50 volts including mains).

5.1.2 Electrical Earthing Schemes

5.1.2.1 Facility Protective Earth Scheme

The protective earth system for the facility is wired by pentant back to the main earth in each service building as

part of the mains supply conductors. This conductor will be connected to the centre-taps of the secondaries of

individual beamline transformers and then distributed radially to the beamlines from this point. This earth is not

intended to be a current carrying conductor (except during a fault).

5.1.2.2 Beamline Protective Earth Scheme

The beamline earth will be distributed to the beamline equipment via the main supply conductors from the

transformers, via the local breaker panel. Sensitive and non-sensitive earths will be separated and only interconnect

as the transformers link to the main building earthing system. Switched mode and variable speed type devices shall

be connected to the non-sensitive earth as part of this cable.

Sharing of equipment across beamlines is discouraged, and very great care needs to be taken. This requires an

Electrical Engineer to advise/design.

All beamline equipment shall be connected to earth in accordance with electrical codes.


13

5.2 Water Systems

There shall be two closed loop water systems available for use at the beamline for component cooling purposes

only. All lines must be labeled as to contents and direction of flow.

The de-ionized (DI) water supply shall be for cooling beamline components including optics. This is a

clean supply, carefully controlled and monitored, also used for supplying accelerator components.

The chilled water supply shall be used for cooling electronics racks and other pieces of non-critical

equipment, such as compressors and furnaces which may be brought on-site by Users.

DI Water System (to be supplied from within the SR)

DI Water Flow (maximum per beamline) 15 gallons/minute (velocity in pipe not to exceed 6ft/sec)

DI Water Flow (average per beamline) 12 gallons/minute

DI Water Temperature 85F+0.2F (29.5C+0.1C)

DI Water Pressure 150 psi max design pressure at 100F and

~100 psi typical working pressure

Chilled Water System (to be supplied from above the SR tunnel roof)

Chilled Water Flow (maximum per beamline) 6 gallons/minute (velocity in pipe not to exceed 6ft/sec).

Chilled Water Flow (average per beamline) 3 gallons/minute.

Chilled Water Temperature 53F nominal, with ~20F temperature rise

(this assumes the removal of ~60% of the 30 kVA per beamline

average electrical load with a 6 gallon/minute flow rate).

Chilled Water Pressure 150 psi max design pressure at 100F and

100-120 psi typical working pressure

Table 3 Water Services Specifications

5.2.1 Facility DI Water Specifications

The de-ionized water shall be supplied to the beamlines for cooling of components (seeing a power loading from x-

ray photons), from the system that supplies the accelerator components. The specification shall be driven by the

needs of the accelerator (specifically the requirement for low resistivity (~1 MΩ-cm +5%)).

All water cooled beamline components shall have water supplied from the DI water system for the accelerator via

flow and return pipes run through the ratchet wall (through a labyrinth) into the FOEs. This system will include a

water filtration unit at the service building to ensure that any contamination in the supply cannot block narrow

passageways in components. The filtration unit shall prevent performance deterioration of any components over the

lifetime of the beamline, including bio-fouling, oxidation and foreign body obstruction.

The inlet and outlet water temperatures (and the conductivity from a facility EPICS PV) shall be monitored by the

Beamline EPS. The temperature sensors and generation of these signals shall be part of the beamline EPS scope of

supply and is not part of the beamline utilities scope of supply.

A stainless steel (grade 304) pipe system shall be used to distribute DI (process) water from the interface point to

the components inside the enclosure(s) and/or other components down the beamline as required. EPDM or Viton

gaskets shall be used for any flange seals where compression fittings or welded joints are impractical.

Radiation resistant plastic such as Poly-Flo or Nylon12 may be used for flexible connections from distribution

manifolds to components where bent stainless steel tube is impractical. All plastic tubing must be stamped with

pressure rating that meets or exceeds the maximum pressure available from the system.


14

Tubing shall be used in conjunction with stainless steel instrumentation type compression ferrule fittings (e.g.

Swagelok or equivalent). Compression fittings interfacing with copper shall utilize appropriate metal to metal

connections such as parallel threaded o-ring connections. Flexible connections shall be kept to a minimum length.

The maximum flow velocity in any water circuit should be less than 2 m/s (for ambient noise minimization).

Output flow meters of very high reliability shall be provided on all process water circuits (e.g. of the Yokogawa or

the KOBOLD RCD-C, or equivalent, type). Valves shall also be included to isolate any parallel process water

circuits. The use of Teflon anywhere is prohibited.

A means to vent air and drain the process water distribution system shall be provided.

Facility to eliminate water hammer or other vibrations shall be provided, if required, in operation.

The beamline EPS shall include a means to detect a fault in the process water circuit (i.e. return flow stops; loss of

water volume due to leak or user usage) and to isolate the water system with an electrically operated valve in the

event of such a leak.

5.2.2 Chilled Water Specifications

The chilled water shall be used for the cooling of equipment racks.

This system shall be plumbed in rigid stainless steel (grade 304); with stainless steel braided flexible hoses only

where needed (e.g. racks needing to move). Fittings shall be Swagelok type.

If required, due to condensation, or risk of condensation, these lines shall be insulated and/or some temperature

control may be required.


15

5.3 Liquid Nitrogen supply

The liquid nitrogen distribution system takes the liquid nitrogen from one or two storage tanks outside the facility

and pipes this to tap-off points adjacent to each of the Insertion Device beamlines (i.e. 30 tap-off points in total).

All lines must be labeled for contents and direction of flow.

This system shall also provide the liquid nitrogen required for the RF system. Background information on the flow

rates, etc. is provided in the Appendix (Section 11).

Average usage Supply Pressure Flow rate

23,000 Gallons / year / beamline

(87,000 l/yr)

This is equivalent to 600l/hr.

Within the range

2.0–3.0 Bar (30–45 psi)

40 Gallons/hr

(150 l/hr) minimum at each beamline

with 50% of spigots open

Table 4 Liquid Nitrogen Services Specifications

5.4.6 General ventilation system

Ventilation of the individual hutches and cabins is required; this will not be part of the CFD responsibilities.

Fans with integral, replaceable, filter elements shall be fitted to the roof of each enclosure.

The fans will force filtered air into the hutch, which will then exit the hutch through various labyrinths

including a dedicated air outlet.

All such fans will be included in the relevant hutch or cabin contract.

The fan shall be able to move air through each enclosure at a rate of at least 6 m3/min. One dedicated air

inlet labyrinth (on the roof) and one dedicated air outlet labyrinth (on the wall, close to the floor) shall be

provided, per hutch, and sized to permit this air flow.

Each fan shall be equipped with variable speed control permitting continuous adjustment from 0% (off) to

100%. Adjustment will be possible only by beamline staff, typically to reduce noise and/or resonances

within the enclosure.

Electrical connection to the mains will be done within the beamline utilities work package.

Care shall be taken to ensure that the vibration criteria are met with the fan running. The vibration criteria

are addressed in the document “Experimental Facilities Requirements, Specifications and Interfaces for the

Ring Building and Experimental Floor”.

6 EXPERIMENTAL FACILITIES UTILITIES INTERFACES

Tables No. 8, 9 and 10, list the interfaces with other WBS elements of the NSLS-II project, except for the

pre-Operations phase (WBS 1.06), which will be considered later. A first order justification for each

interface is given here where necessary, i.e. when it is not obvious from the attached WBS dictionary

definition. The interfaces identified here are defined and managed through meetings, software tools and

interface control documents.

6.1 Interfaces with the ASD

Table 9 Interfaces of WBS element 1.04.01.02, XFD Utilities with the ASD (WBS 1.03)

WBS Title Dictionary Definition

1.03.04.08.02

Storage Ring

Electrical

Utilities

Design, specify, and procure storage ring electrical utilities. This

includes equipment enclosures, cable tray, AC power connections,

and special AC power. See the level-6 WBS entry for more

detailed descriptions. The procurement for electric utilities will

almost be standard commercial products. The racks will have some

simple factory modifications to minimize our labor costs. All

procurements will be done through a request for proposal buy.

This is so the project gets the exact technical specification and

delivery schedules needed, even through the components are

standard products

Reason: Although the electrical utilities are provided by CFD,

ASD provides design and specifications for the transformers and

load panels powering all beamline equipments. See also all WBS

elements at a lower level

1.03.04.08.03

Storage Ring

Mechanical

Utilities

Design, procure, and fabricate the mechanical utilities (process

water and compressed gas) associated with the storage ring. This

will include five process water pumping systems for each

Mechanical Equipment Room (MER) and one pumping system for

the storage ring RF system. There will be nitrogen gas

compressors also located in the MER to supply compressed gas for

various process valve operation (see the level-6 WBS entries,

below, for additional details).

Reason: ASD provides the process DI water system and

compressed N2-gas for the Experimental Facilities. Other, WBS

elements below 1.03.04.08.03, that specifically address DI water

and G-N2 must also be considered n developing this interface.

1.03.04.09.01

Storage Ring

Installation &

Test of

Mechanical

Utilities

Install and test all mechanical and electrical components

associated with the Storage Ring Water System and Storage Ring

Compressed Gas System. This includes all piping, heat

exchangers, pumps, and valves for each of the five Mechanical

Equipment Rooms (MERs), the distribution system associated

with each MER, and the connections to all specific components,

excluding the Injection System (which is under a separate WBS,

1.3.3.5.1). Labor will consist of both engineering and technical

staff.

This interface naturally follows from the above-identified interface

with 1.03.04.08.02.

1.03.04.09.02

Storage Ring

Installation of

Electrical

Install storage ring electrical utilities, which include all equipment

enclosures, cable trays, AC power connections, and special AC

power. Also includes the manpower to pull all subsystem cables


22

Utilities for the entire storage ring. (Each subsystem is responsible to

terminate its own cables.) This WBS entry is mostly for

installation labor.

This interface naturally follows from the above-identified interface

with 1.03.04.08.03.

6.2 Interfaces with the CFD

WBS Title Dictionary Definition

1.05.02

Conventional

Facilities

Engineering and

Design (Marty

Fallier)

Execution of engineering and design of NSLS-II buildings,

utilities, and improvements to land by developing design

requirements, preparing design drawings and specifications for

construction contracts, and providing engineering support during

the construction phase, to assure proper execution of the design

and complete as-built documentation.

Reason: beamline-utilities interfaces need to be considered as early

as possible, during the building design phase. This interface

extends to all WBS elements branching from this, namely the

Title-I and Title-II design activities until the final design is reached

and approved.

1.05.03.06 Ring Building

The building is divided into five pentants with a service building

within each pentant, and is connected to each of the other

buildings identified in separate WBS entries. The Ring Building

spaces include the accelerator tunnel, power supply and utility

service gallery on top of the storage ring tunnel, experimental floor

beamline areas, and service buildings totaling ~294,000 GSF.

Included are the building enclosure, all building finishes, and

distribution of services for the experimental and accelerator areas

within the building. Initial beamline utility services will be

distributed to pentants 1 and 5 and partially in pentants 2 and 4.

The Ring Building is the functional center of the facility and is the

primary element of the Ring Building contract.

Reason: beamline utilities services distribution. This interface

extends to all sub-activities branching from this WBS element,

namely 1.05.03.06.01 through 1.05.03.06.05, referring to the five

pentants in which the ring building is subdivided.

1.05.06.01

Ring Building

Commissioning

(Stephen Sawch)

This activity provides inspection, testing, O&M training, and start-

up commissioning services for the Ring Building HVAC systems

and services, including the Service buildings.

Reason: utilities commissioning phase. This will just verify that

the systems are installed in accordance with the construction

drawings and specifications. The beamlines will be installed much

later - several years after the ring bldg construction is done -

commissioning and calibration at this time must be done in concert

with operational staff because the contractor will be gone from the

site. It is also something that is best done with operating staff

given the imprecise nature of what is required and when.

6.3 Interfaces with ES&H

Table 11 Interfaces of WBS element 1.04.01.02, XFD Utilities with ES&H (WBS 1.01.02)

1.01.02.01 ESH

Management

This function provides ESH management for safety & training

related activities associated with the NSLS-II R&D program,

the NSLS-II construction program, and the NSLS-II

commissioning activities. It specifically includes: 1.

Preparation of ESH manuals, procedures, etc. 2. Providing

support and guidance to NSLS-II staff regarding ESH and

training requirements 3. Conducting safety evaluations of

design to ensure compliance with DOE and BNL ESH

requirements 4. Monitoring workplace activities and conditions

to ensure compliance w/ DOE & BNL ESH. Determination of

ESH related training requirements, tracking training

compliance, and provision of NSLS-II ESH training for staff

members. 6. Preparation of safety assessment documents

needed to support CD-1, 2, 3, 4a, & 4b. 7. Coordination and

follow up of required ESH reviews associated with beneficial

occupancy and Accelerator Readiness Reviews.

The installation of beamline utilities raises safety issues:

electrical, high-pressure gases, etc. Compliance to safety

regulation requires coordination w/ ESS&H.

1.01.02.02 Shielding

Analysis

This WBS activity provides radiological support for NSLS-II

design and commissioning activities. It includes: 1. the

preparation of shielding analyses for the accelerator enclosures

and beamlines 2. Specification of required shielding 3. review

of design for radiological shielding to determine compliance

with BNL requirements. 4. Support and monitor commissioning

activities, including evaluations of shielding and radiation fields

generated during commissioning studies, evaluation of dose to

equipment and components as a result of operational beam

losses and evaluation of induced activity in machine

components to determine handling and storage requirements.

The installation of beamline utilities requires drilling into the

enclosures shielding walls. Radiation protection issues [1, 2].

8 APPENDIX 1. ELECTRICAL POWER CONSUMPTION ESTIMATE.

Comments from Oxford Danfysik

To answer your question in the absence of anything else please find my rule of thumb measures:-

Mains power is complex and depends upon the components.

I would budget 50W/stepper axis plus 100W per large component - Mirror or DCM. The sizing of the circuit breakers should reflect this.

The sizing for the air-conditioning should be 20W/stepper axis plus 100W per large component because you assume 40% of motors are operating at any one time.

Further Oxford Danfysik comments from Julian Adams - PX BLS ASP.

The 240V version MCS8 is rated at 6A (8 motor control channels 1.5kVA)

In reality it uses about 2 A continuous and about 4A peak (ie about 60W/channel idle and 120W/channel peak).

Comments from FMB (very detailed spreadsheet for SXR Beamline), have been incorporated below.

The control system operates all components (i.e. also the ion pumps) with exception of the heat exchanger and the bakeout system.

The given power consumption of 11 kW is a safe value for the switch on moment of the system

(approx. the first half second) because there are typically a lot of inductances (Transformators etc.) in a control system.

Therefore time delayed fuses are necessary. The actual consumption is clearly lower but we don't know the correct amount.

The Heat exchanger (Haskris) needs 3 x 415 V x 5A because of the three-phase motor inside.

Comments from ASP (8-axis stepper controller built in-house from Galil modules)

Rated power draw is 600W/8-axes. In practice never anywhere close to this. Allow XX W/motor axis.

Comments from ACCEL 240V current draw tbc.

28

Note; following discussions with Sushil Sharma (AJB, 14th Jan 2008), it was proposed that the number of water

circuits be reduced by 40% over those recommended by the various beamline supply companies. The rationale for

this is that the pressure differential between flow and return is 80psi (100psi flow and 20 psi return), which is

higher than usual. Additionally, several components on the beamline are “non-critical” e.g. fixed masks, windows,

and possibly, white beam slits. Connecting non-critical circuits in series after the more critical components makes

good use of the water, and minimizes the use of flow sensors – APS experience has been that flow sensors cause

the majority of false trips to EPS.

The specifications for the DI water system are driven by the accelerator.

In summary, and for information only, the following specifications are expected for the DI water system;

Resistivity to be >1 MΩ-cm + 5% (beamline components can actually tolerate lower resistivity, but this is driven by

the accelerator (magnets and RF) requirements for minimization of leakage currents).

The pH value shall be 7.5 + 0.2. Naturally the water will tend to be slightly acidic due to Carbonic acid from CO2

absorption, this needs to be avoided.

The oxygen content shall be 5-10 ppb in order to minimize the corrosion rate.

10 APPENDIX 3. CHILLED WATER CONSUMPTION ESTIMATE.

A typical beamline will have the following racks;

Hutch Quantity Rack function

Optics 2 Stepper controllers, ion pumps, EPS, UPS, IOCs

End station 4 Stepper controllers for end station tables, diffractometers etc.

Detector electronics, IOC and DA.

11 APPENDIX 4. LIQUID NITROGEN CONSUMPTION ESTIMATE.

The liquid nitrogen consumption varies enormously depending on the beamline source, etc. The following table

attempts to quantify the LN2 consumption for the full facility, and set some sensible flow rates per beamline. The

typical operating pressure will be ~40psi.

Note for information only. It is expected that the nominal inside diameter of the liquid nitrogen pipe (i.e. not

including the insulation and vacuum jacket) will be ~1”. Experience at the APS (source Chet Touton, Quality

Cryogenics, GA) has shown that tap off points should be sized as follows;

1” nominal inside diameter for the inner pipe is adequate for 17 GPM flow rates, and

½” nominal inside diameter pipe is adequate for 6 GPM;

A maximum pipe run of 600’ was recommended, and the maximum size of a vertical tank was stated to be 12000

gallons. This information is being used by the architects to design the system.

10 Cryojet/Cryostream + robot (note 1) 40 W/ea gives 400 W ~1l/hr consumption

20 LN2 cryostats (note 2) 40 W/ea gives 800 W ~1l/hr consumption

Total power 26585 W

Total LN2 consumption for beamlines and experimental stations is 598 l/hr at 22.5 cc/hr liquid boil off per watt

rounded 598 l/hr

5239923 l/year for the whole facility, fully built out

or…. 1.4 million gallons/year

which is…. 22982 gallons/beamline/year (see note 3)

assuming 60 beamlines in completed facility

APS actual consumption 17000 gallons/beamline/year

APS slightly lower consumption accounted for by their lack of DWs.

Notes

1 Cryojet / Cryostream needed for all PX lines - guesstimate qty 5, and then double to cover robot consumption.

2 LN2 cryostats needed for PD, XAFS, SXR, plus detectors and sample stage

3 Assuming a tank capacity of (litres) 60000 the number of fills p.a. is 87 or 1.7 per week (resonable)

4 ASP specified 150l/hr minimum flow at each beamline with all spigots open - see below.

In summary;

LN2 delivery rate at each Beamline 150 l/hr (minimum with 50% of spigots open - ie a maximum draw rate of no more that 5000l/hr)

12 APPENDIX 5. GASEOUS NITROGEN AND COMPRESSED AIR CONSUMPTION

ESTIMATE.

The consumption of compressed air is relatively small, and mainly intermittent. Typically a ½” nominal inside

diameter pipe is adequate, with a typical supply pressure of 80-100 psi.

Typical devices on a beamline requiring compressed air include:

Gate valves

Shutters

Possible air bearing for the IXS spectrometer(s) – comparison with SPRing8 data showed this was a very

low flow rate, connections being made with 4 x 6mm diameter plastic tubes.

Air bearings for PX beamline goniometers.

The consumption of compressed nitrogen is very small, and intermittent. Typically a ½” nominal inside diameter

pipe is adequate, with a typical supply pressure of ~30 psi.

Typical devices on a beamline requiring nitrogen gas include:

Purge devices (for IR microscopes)

Chambers requiring inert gas

Vacuum section bleed-ups

Experiments requiring nitrogen gas as an inert medium.

13 APPENDIX 6. TEMPERATURE SENSORS BACKGROUND INFORMATION.

All hutches and cabins shall be fitted with ambient temperature sensors in a small ventilated enclosure.

Temperature sensor type TBD

The sensors shall be wired back to the beamline control racks (outside the hutch)

The sensors can be used for monitoring and/or control of hutch temperature as required.

14 APPENDIX 7. OXYGEN DEPLETION ALARMS BACKGROUND INFORMATION.

Oxygen depletion alarms shall be fitted to all hutches or cabins where LN2 or gaseous nitrogen is (or could be)

present. The hazard is possible with a simple small Dewar in a potentially enclosed space; however, the hazard

becomes significantly greater with plumbed liquid nitrogen where a line rupture could lead to the spillage of

dangerous volumes of liquid.

Care need to be taken to ensure that the ODH sensor is sensitive to nitrogen and helium gases.

The sensors shall be wall mounted at approx 1-2m height (in accordance with the manufacturer’s instructions) with

an alarm external to the hutch or cabin.

The budgeted cost of Oxygen depletion sensors is ~$2000/enclosure, or about $4000/beamline max.

A "standard" stand alone system covering a single experiment station, cabin or FOE has a typical historical cost of

~$2500 per cabin, this includes a strobe/siren, and a spare head (aim for one spare head per four installed heads),

and commissioning work (as well as the first year of calibration, after which facility staff must do scheduled

maintenance). Facility staff or utilities contractors can do the installation which is simple, and requires only about

10m of standard instrument cable (and takes less than 4 hours per hutch).
